SOFA-BED.

Specification of IiettersPatent. Patented NOV. 11, .1919.

Application filed November 8, 1916. Serial No. 180,109.;

State of California, have inventeda new and useful Sofa-Bed, of which the following is a specification.

My invention relates to that typeof folding bed generally known as the davenport or sofa bed.

An object of my invention is to provide a sofa bed which in its folded position is capable of containing a full size upholstered mattress.

Another object of my invention is to provide a sofa bed in the folded position of which the mattress and bed frames are folded behind the seat.

The invention possesses other features of advantage, some of which, with the foregoing, will be set IEOIthl in the following description of the preferred form of my invention which is illustrated in the drawings accompanying and forming part of the specification. It isto be understood that I do not limit myself to the showing made by the said drawings and description, as I may adopt variations of the preferred form within the scope of my invention as set forth in the claims.

Referring to the drawings:

Figure 1 is across section of the sofa bed when unfolded to form a bed. A portion of the upholstered mattress is broken away to disclose the structure.

Fig. 2 is a cross section of the sofa bed when folded to form a sofa. The upholstered mattress is omitted to better disclose the structure.

Fig. 3 is a cross section of the sofa bed on a smaller scale showing the upholstered mattress in place.

My invention comprises a main frame or stationary structure 4: inwhich a seat frame 5 is arranged. Preferably the seat. frame is mounted on'pivots 6 set in the stationary structure so that it can be turned up about the pivots to give access to a space .7 below the seat in which space, bed clothes are conveniently kept when the apparatus is closed.

The seat frame 5 is fitted with suitable upholstery 8 to provide a comfortable seat and the weight of theseat s carried y the pi ots 5 and the orossrail 12 which is part of the stationary structure.

Arranged behind the seat in an upright position is a bed frame section 14, Fig. 2,

so mounted in the stationary structure that it may be moved into a horizontal position above theseat frame as shown in Fig. 1. The means for accomplishing this mounting include'a curved arm 15 rigidly attached to the section 14:. At its end the arm is attached by the pivotal connection 16 to the llnk 17 which in turn is mounted on the pivot 19- set in the stationary structure. The link 17 therefore carries the weight of the sectionlt. The pivot 16 conveniently may travel in arcs between the slats 5 of the seat frame, and the rear wall 5' of the seat frame is suitably recessed to permit a free movement of the arms 15 as shown in Flgsl 1 and 2; and it is obvious without specific illustration that the links 17 may be shortened a trifle so that the pivots 16 lie below the plane of theslats and the curve of the arms15 modified so'that recessingof the rear wall '5 is unnecessary. The placing of the pivots 16 below the seat frame rather than at the ends of the seat frame is of advantage since it saves valuable space atthe ends of the seat frame. vMeans are provided cooperating with the link 17 for controlling is disposed on each end of the stationary structure 1 and rollers 22 rotatably mounted near the lower edge of the section engage a groove 24 formed in the tracks 21. As the section is moved from the upright to the horizontal position about the movable pivot 16, the rollers 22 move upward in the tracks 21, thus definitely positioning the section at all times in respect of the stationary structure.

Foldably attached to th'e'bed frame section 14 is a second section 26 Preferably a short section 27 is interposed between sections 14 and 26 so as to provide a space therebetween in which the upholstered mattress 28 may lie in the" folded position of the parts. The mattress is preferably attached in any suitable'way to the bed section frames or to the spring fabric 29. stretched in the frames. Stops 31 are provided on the short section .27 that t e three sect ns when unfolded are prevented from moving past the alined position shown in Fig.

A stiffening rod; 32 is connected to the sides-of the section 27 to keep thenrfroni being displaced inwardly under the tension of the spring and the weight of the occupant of the bed. The rod is arched downwardly so as to carry it below the normal sagging of the spring and is .pivotally at- I tached to the sides of the section 27 onthe outside, so that p when the frames are folded as shown in Fig. 2, it lies about the upper edge of the frame 14. v

Aleg -33 islpivoted upon each side near .15 the outer end of the section 26 to support 3 the section when the bed is unfolded and the section is extended inlme with the sections 14 and 27. Each leg is provided with an -30 to hold the leg 33 in the extended position or the hook 36in engagement with the pin 37 as the .case may be... 4

eans are provided section 14 inihorizontal positon and thus keeping the extended sections in horizontal alinementtherewith. For this purpose I i, prefer to make useiof the back name 41 of thesofa. The backframe is suitably upholstered ,to provide a comfortable back for the sofaand in the folded position effectively conceals thefolding bed sections. At its lower end it is pivoted at 42 to an arm 43 formed integral with the frame 14. About thisfpivot it is allowed a limited mo- 45 tion bythe links'44, one pivoted to each side .of the frame at 45. Each link is formed v with a slot 47 terminating in :a notch 48. 7 When the'back frame is pulled outwardly the I notch is engaged on a pin 51 set in the frame 50.}14. -This holds the back frame inv the for- ;ward position indicated in the dottedlines 41 ofFig. 2, and when the unit inclosing the mattress 28 is pulled forward into the horizontal. position theback frame engages the pads 53 on the seat frame and forms a .support'Qforthe frame 14. It is seen that in 6 this construction sufficient space is left clear 1 below the; frame 14 to accommodate the normal amount of sag in the spring 29. A

V spring 54 attached to the link 44 tends to prevent its accidental disengagement from i :The stationary structure-is provided with a top board55 and preferably this is hinged at the rear so that it can be thrown up out for supporting the of the way to clear the back frame preparatory to opening the bed. Preferably a heavy coiled spring 57 is connected to the stationary structure and the section 14, whereby the weight of the section and attached folding members is largely balanced by the pull of the spring. he unfolding and folding movements are thus easily effected with but little effort onthe part of the operator.

Assuming the sofa bed to be in the closed or folded position shown in Fig. 2; the top board 55 is first thrown back so that the top of the back frame 41 may be grasped and pulled forward into the position of the" dotted lines 41 Continuing the outward pull, the unit comprising the locked folded frames inclosing the mattress swings upwardly about the movable pivot 16 to a horizontal position where it is supported by the combined effects of the rollers 22 en gagincr the tracks 21, the link 17 and the extende :back frame 41 resting on the seat frame. The legs 33 are next lifted to (11$- engage the hooks 36 and unlock the two frames 14 and 26. Frame 26 is then unfolded, moving together with the intermediate section 27 into horizontal alinement with section 14. The mattress 28 unfolds with the frames to which it is attached and the parts are then in position as shown in Fig. 1.

,To fold up the structure, the frame 26 is turned over upon the frame 14 to inclose the mattress therebetween and the legs pulled down to lock the frames together into a single unit, which is then lifted by grasping the outer end of the back frame 41 and allowed I to'slip back into the upright position shown .in Fig. 2. When the unit has nearly completed this movement, a pin 58 on the link 44 engages a curved ledge 59 on the stationary structure, riding up thereon and thereby releasing the link from the stop pin 51. This permits the back frame to move backwardly into its normal position. The top board 55 'is next closed down and the parts are then in the folded position shown in Fig. 2, the

frames resting against the stop 61.
